Definitions
- waveguide absorbers are used, e.g. are known from the "Taschenbuch der Hochfrequenztechnik", H. Meinke and F. W. Gundlach, 3rd edition, 1868, pages 443-445. This publication does not disclose the means by which the bodies made of absorber material arranged in the waveguide are fixed.
- the invention has the advantage that none of the usual substances, such as glue or solder, are used for fixing the absorber body, which often do not withstand very high thermal or mechanical stress.
- the Mechanical effort with the waveguide absorber according to the invention is very low.
- the figure shows a side view of a rectangular waveguide 1, which is provided at one end with a flange 2 and the other end is closed with a cover 3.
- a body 4 is inserted, which at least partially consists of a temperature-resistant absorber material (e.g. silicon carbide).
- the body 4 extends with a partial area over the entire waveguide height and has the shape of a wedge.
- the absorber body can have any other shape; it hangs e.g. on the electrical requirements and on the installation position in the waveguide. It is only decisive that the body extends at least in regions over the entire waveguide height (or the entire waveguide diameter in the case of a circular waveguide), so that it can be clamped between opposing wall regions of the waveguide.
- a waveguide wall 5 is reduced in thickness at least in the area lying on the body 4 so that this area is flexible. If pressure is exerted on this flexible wall area 5, the body 4 is pressed against the opposite rigid waveguide wall 6. This creates a good heat-conductive contact of the body 4 with this waveguide wall 6, on the outside according to the illustrated embodiment, a cooling system, for. B. a heat pipe is arranged.
